WILLIAMKB. BABY, or sr. PETERSBURG, ,RUSSIIIA;

ANNULAR ROTATING rUnNAon.

Be it known that I, VVILLIAM B. BABY, a citizen of the United States of America, and Petersburg, Russia, my post-oflice address being 7 Isaacs Place, St. have invented certain new and useful Improvement's'in Annular Rotating Furnaces, of-which the following is a speciand decreases fication. Y

My invention relates .to certain new and useful improvements in annular rotating furnaces, and has for its object to provide a furnace mtendedfor' the burning of sundry materials, (brick, cement, et'c.,) as well as for other purposes.

To these ends the invention consists in the novel details of construction and combinations of closed an claims.

Referring to the accompanying drawings, forming a partpf this'specification, in which like numerals designate like parts in all the views :-Figure .1, represents a vertical sec tion of the' furnace on the line E-F, of Fig. 2'; Fig. 2, is a horizontal section of the furnace taken on the line 0-D, 'of Fig. 1; Fig. 3, is a vertical section taken on the line GH, of Fig. 4 and Fig. 4, is a. horizontal section taken on,the line A-B of g. 1.

The working part 1 of the furna-J consists of a suitably supported rotating disk, provided with a large central opening, as shown in Fig. 2, thus forming in fact a large flat ring.

2 and 2' represent two concentric circular Walls covered With an arch 3. The Whole furnace is placed in a casing 4 of stone ma sonry, and is separated by a narrow passage 5, the air in which serves-as an insulator thereby the loss of heat from arts more fully hereinafter dis- 5 particularly pointed out-in the radiation.

In the center of the circle Iormed by the Working part of the furnace and the casln a stack 6 is arranged, into which the pro nets of combustion enter through a horizonta]. passage 7, see Figs. 1 to 4, eading from the upper part of the worklng space of the furnace.

The rotation of the Working an11ular ring K of the furnace is effected wlth the aid of the gear wheel 8, Fig. 2, which engages teeth carried on the outer circumference of the said ring K, and on the axis of this gear wheel 8 may be provided a pulley, not shown, for the application of power.

Pieces of U beams l010, arranged parallel and radially of the ring K divide. the entire surface of the frame into equal parts and are fastened in pairs on the upper part of said'ring. T beams-11 are inserted in the U beams flange'downward, while their bars are embedded into the movable masonry; structures 12 been substantially the whole of the working part of the furnace, as shown in Fig. 3. The heating of the material takes place on the upper portions.

Below the ring K are concentric circular metal supports 15, L-shaped in cross section, in which rest concentric rails 14, supporting disk shaped pieces having the tapering projections 13 resting on said rails, as shown. Said disk shaped pieces as plainlyshown in Figs. 1 and 2, suitably support,; as by ball in turn, support the annular 'ng K, as illustrated. It is preferred to provide. only three ballsbetween said upper and lower disk shaped pieces. 'The taper projections 13 roll on the circular rails 14 and thereby do away with sliding friction, which otherwise would absorb considerable powerin the case of a furnace structure, such as shown. The side shift of the ring K is prevented by the concentric circular rails '14, 011 which the lower parts of the lower disks roll. As the taper projections 13 of said disks roll on the rails 14, they at the same time, rotate the ball bearings above the same, as will be furnace, as shown, and becoming heated it reaches the openings 16, where it encounters the air inv the furnace and burns, as will be readily understood. The air, which may be regulated in any suitable manner, enters the furnace at the point 18, and moves above the heated material carried by the structures 32, cooling it gradually but becoming heated itself in its passage to the opening 16. Such independent and 'eshaped, pixes, which,

bearings between said upper 3. In a rotating furnace, the combination of a, supporting ring heated air increases the heat effect of the fuel in the manner well known. The part of the arch near the openings 16 is made readily removable so as to afford the possibility of replacement in the case of its being burned out; while the rest radially disposed fails on said ring on which said structures may be moved; upper disks and lower disks provided with tapered proof the arch is made more permanent as it is less apt-to getburned out. Some of the brick ings between said upper and lower disks; concentric rails on which said tapered projections roll; concentric supports for said last mentioned rails; means for feeding air and gas into said furnace; and means for heating both of said gases before igniting the same, substantially as described.

4:. In a rotating furnace,-the combination of a supporting ring K; tures for holding carried by said ring; horizontally disposed upper disks and horizontally disposed lower disks for supporting said ring; ball bearings between said upper and lower disks; a stack around-which said ring revolves; a passage 7 connecting the with said stack; and means for admitting gaseous fuel to said furnace, substantially as described.

5. In a rotating of a supporting rin'g K; independent strucwithdrawn from the furnace on the-rails 10 The rentering of the furnace may be acanother pair of beams or rails 10". A vertical wall 19 is provided oppositethe central part of the platform, this wall separating the right side of the furnace through which the air enters, from the left from which the products of combustion come out.

The proposed furnace can serve for the burning of finely divided and hard bodies, for tempering and annealing of lass, for the heating of metals intended for urther treatment and for the baking of breadfetc.
